ECM Terminals and Reference ValueEBS01KIT
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.

Injector adjustment value indicates manufacturing tolerance and the value is printed on the top of fuel injec-
tor.The injector adjustment value which is correctly stored in ECM is needed for precise fuel injection control.
A performance of emission control and a drivability may effect when there is a mismatch between the following
two values.
